BUCKLE.

Specification of Letters Patent.

[Patented Nov. 10, 1914.

Application filed March 29, 1913. Serial No. 757,695.

To all whom it may concern Be it known that I, ERIK AUGUST HoRLrN, a subject of the King of Sweden, residing at Tunnelgatan 3, Stockholm, Sweden, have invented a new and useful Buckle, of which the following is a specification.

My invention relates to a buckle for belts, bands, straps, etc., for any purpose for in stance on neck-ties, brace-bands, garters, skates, trunks, harnesses, saddles, etc.

The object of my invention is to afford a buckle, which can be used with the same efiect on belts of different thickness and which is so constructed that the belt can be locked, automatically or not, exactly in the tightened position without first making any dead return motion.

The buckle is provided with a slidable key or wedge by means of which the buckle is adjusted so as to fit the thiclmess of the belt.

In the drawing, Figures 1 and 2 are plan views with the wedge in different positions and Fig. 3 a section on the dotted line of Fig. 2.

The buckle consists of two pieces, viz., a plate or frame a and a key or wedge 70, which is slidable thereon, so as to adjust the width of an opening for the belt between the front edge Z of the key and the edge (Z of a slot e in the frame or body plate so that the belt can be locked or jammed between said edges.

If the key is a little springy or if its front edge is adapted to make a slight movement from the frame, the belt can be tightened and automatically locked in the tightened position without changing the position of the key provided that this is adjusted in beforehand so as to fit the thickness of the belt. This is due to the fact that a pull on the free end of the belt will cause a slight bending or rocking of the key, whereby the slot between the edges Z and 03 is a trifle enlarged so as to permit the outward passage of the belt, while a movement of the belt in opposite direction is impossible as the key instantly rocks back and locks the belt when the pull ceases.

As seen in Fig. 3 the slot 6 in the plate a is made by cutting and bending upward a rectangular tongue 7), so that the edge d is enlarged upward and rounded off, thus forming a broad and even bearing face for the belt. This tongue is also adapted to strengthen the plate so that a thin plate can be used. If the buckle is to be fastened by means of a slot f near the rear end of the plate a, this slot may be made in-the same way by cutting and folding a tongue 0 as shown. v

The key 70' may be guided in any suitable way. In the form shown its rear portion has a'slot 0 parallel with the rear edge so as to form a linear guide-piece s which slides in an oblique guide 9- on the plate a, so that the front edge Z remainsparallel with the edge (Z. This guide may consist of atongue, cut from the plate a and bent around the guide piece .9 as shown. If the slot 0 is so narrow that the key k can bear also against the outside of the guide 9, the keyrnay be made of thin sheetmetal.

"In order to facilitate the adjustment of the keyulc it may be provided with one or more lugs m n,- which in the form shown consist of upwardly bent end portions. Also the front edge Z may be bent upward if desired so as to enlarge the bearing surface and strengthen the key.

In use the belt is inserted in the slot e and tightened and then the key is moved forward so as to press the belt against the edge d. If the belt is to be still more tightened this will be effected. by simply pulling its free end without moving the key.

When the belt is to be loosened, the key should first be moved backward so as to widen the slot 6.

The plate a may be fastened or connected to the belt Or other object in any convenient way for instance by means of a slot f as shown in Figs. 1 and 2 or by means of holes so as to be sewed or riveted.

The word belt in this description and in the following claims stands as a representative for belts, straps, bands, etc., of all kinds and for all purposes.

What I claim is: 1

1. A buckle comprising a base formed with a transverse slot, through which a strap is adapted to be passed endwise, a member mounted on the base, said member having an edge adjacent and parallel to the transverse slot and adapted to clamp a strap passed through the slot, and means for causing a relative oblique sliding movement between said base and the member to bring the transverse edge of the member and one edge of the slot toward each other when either the member or the base is moved.

2. A buckle comprising a base formed with a transverse slot, through which a strap is adapted to be passed endwise, one wall of said slot being bent upwardly, a slidable member mounted on the base, said member having one edge parallel with and adjacent to the bent wall of the slot, said member having a slot which is oblique to the bent wall of the slot, and an oblique guide on the base to engage in the oblique slot to form a guide for said member, wherebv when the member is moved the parallel edge of the member will move parallel with and longitudinally toward one edge of the slot to clamp the strap.

3. A buckle comprising a base formed with a slot through which a strap is adapted to be passed endwise, one wall of the slot being bent upwardly, an oblique guide on the base, and a member having an oblique slot to receive the guide, said member loosely fitting on the guide to permit of a rocking movement, the edge of the member being parallel with and adjacent the bent Wall of slot and adapted to clamp the strap passed through the slot, against the bent wall.

t. A buckle comprising a base formed with a transverse slot, a rocking and obliquely slidable member mounted on the base adjacent to and cooperating with one wall of the slot, and means for mounting the member to permit the oblique and rocking movements.

5. A buckle comprising a base formed with a slot, through which a strap is-adapted to be passed endwise, one wall of the slot being bent outwardly and rearwardly, an oblique guide on the base, a member having an oblique slot to receive the guide, said member cooperating with the bent wall of the slot, the guide and slot permitting the member to be moved obliquely across the base and rocked toward and from the slot in the base to bind a strap against the upwardly and rearwardly bent wall.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
